SPEED REGULATOR.

Application led September 14, 1925. Serial No. 56,341.

This invention relates to transmission mechanism or drive devices and has for its object the provision of a novel mechanism by means of which a driven shaft may be operated at a certain desired speed, the speed being controlled automatically in ac` cordance with the rotation of the driven shaft, the invention being particularly well adapted for use in driving a generator or the like whereby when the driven shaft rotates above a certain predetermined speed the drive shaft will be automatically locked thereto for rotation therewith.

An important object is to provide an automatic regulator for the speed of a driven shaft such as that of a generator or the like whereby the driven shaft will be rotated at a requisite speed even though the speed of the driven shaft of the regulator be greatly reduced, while at the same time when the speed of the driven shaft is increased greatly the drive shaft will be automatically locked thereto.

An additional object is -to provide a de- -vice of this character which will be comparatively simple and inexpensive-in manufacture, easy to install, positive in action, efficient and durable in service, and a general improvement in the art. v

With the above and other objects and advantages in view, the invention consists in the details of construction and arrange ment of parts to bel hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which Figure 1 is an elevation of the device with one end plate of the casing removed and the shaft in section.

Figure 2 is a section taken on the line 2N2 of 'Figure 1.

Figure 3 is a cross section on the line 3-3 of Figure 2.

Figure 4 is a cross section on the line 4-4 of Figure 2.

Figure 5 is a cross section on the line 5 5 of Figure 2.

Figure 6 is a detail sec-tion on the line 6-6 of Figure 4.

Figure 7 is a detail perspective view of oneJ of the fiy weights, and

Figure 8 is a detailperspective view of one of the pawls. Y

Figure 9 is a detail perspective view of another one of the pawls.

Figure 10 is a detail elevation of one of the cup-like members.

Referring more particularly to the drawings the numeral 10 designates a casing wiich may be of any desired or necessary size, shape and material and which is provided with a removable end plate 11. Journaled through the casing is a shaft 12 constituting the driven shaft and keyed or otherwise secured thereon .is a disk 13 having a hub portion 14. The shaft 12 is driven by any suitable transmission mechanism. Mounted against one face of this disk is a cuplilre member 15 having a iiange 16 at its outer periphery7 and disposed againstvthe opposite face is a similar cup member 17 having aflange 1S at its outer periphery. The fianges 16 and 18 extend in opposite directions. Y Y

Disposed against the outer face of the cup member 15 are dogs 1-9 and disposed vao'ainst the corres ondinwface of the cu s P e member 17 are dogs 20. These dogs are all held in place by pivot members 21 which pass therethrough and through the disk 13. Thilo a certain typeof pivot member is disclosed it is quite obvious that there may be variations in this respect. The dogs 19 and 20 are formed respectively with laterally extending lugs 22 and 23 which of course extend in oppositedirections, and the dogs 19 are formed with pins 24 projecting in a direction opposite the dogs 22, passing through slots 25 in the disk and cup mehr bers and passing through holes 26 in the dogs 20. Secured to the inner periphery of the flange 16 of the cup member 15 are curved leaf springs 27 which areengaged by the lugs 22 for normally urging the dogs 19 in one direction. As these dogs |19 are connected with the dogs 20 by means of the pins 24 engaging within the holes 26 it is quite evident that the dogs 2() will be controlled in the same manner as the dogs' 19.

The numeral 28 designates the drive shaft which surrounds and which is rotatable upon the shaft 12 and independently thereof. This shaft 2S is intended to be coupled directly to the generator or the like to be operated, and carries a gear 29 meshing with a gear 30 on a counter shaft 31 journaled in the casing in parallel relation to the drive and driven shafts. ries a gear 82 meshing witha ,gear keyed or otherwise secured at 34 upon the hub 35 of a drum 36. Keyed or otherwise secured upon the drive shaft 28 is a clutch The gear 30 car-v element 37 of a ratchet-like nature having shoulders 38 and curved or cam surfaces 39 therebetween.

Located Within the cup member 17 and pivoted thereto as shown at Il() are fly Weights Ll1 formed With shoe portions 42 adapted to bear upon the drum 35 and urged normally into engagement therewith by means of leaf springs 13 scoured to the inner periphery of the iiange 18 of the cup member 17.

ln the operation, it will be observed that when the driven shaft 1Q is rotated the interineshing gears and 30 and and will be effected by the rotation of the drinn 36 and as the shoe portions 42 ofthe fly Weights in cn ement with the drum andas these fly We nits are carried by the disk 13 secured to the driven shaf it is obvious that the drive shaft 23 n* l ze rotated a speed greater than that t 12 i l l of the driven shaft 12, the relation depending upon the ratio of the gears and 33. VJhen the speed of the driven shaft 12 is increased and reaches a certain predetermined rate, the fly Weights t1 will swing outwardly under the influence of centrifugal force and the shoe portions i-2 will disengage the drum 36, thus breaking the drive connection. At the same time, the dogs 19 and 2O ivillV swing outwardly under the influence of centrifugal force and against the resistance of the springs 27. fis the dogs 19 and 2O are connected for simultaneous movement, it will be observed that the lugs 23 of the dogs 2O ivill move tovvard the axis of the drive and driven shaft-s and Will engage with the shoulders 38 on the clutch member 3'?. When this occurs, it is obvious that the drive shaft and driven shafts will be locked together for rotation at the same speed, thus giving a direct drive. When the speed of rotation of the driven shaft increases, the dogs engage the clutch member and the fly Weights with the shoe portions thereon disenga-,gcs the drum for automatically shifting the drive connection and decreasing` the speed. lt is believed that the construction, operation, general utility and advantages of the mechanism will be readily apparent to one skilled in the art Without further eX- planation..

lVhile l have shown and described the preferred embodiment of the invention, it should be understood that I' reserve the right to malte such changes in the form, construction and varranzgfement of parts as will not depart from the spirit of the invention or the scope of the snbjoined. claims.

Having thus describedV the invention, I claim:

1. A. speed regulating mechanism coinprising the combination with. drive and friction drum increasing c by the driren shaft tion rum, a support cariven siiaft, inwardly spring pressed Hy Weights carried by the support and coopeinting` with said drum for protating a the drive shaft, a disk Within the casing on the driven shaft, fly Weights'carried by the dish and coacting ivith thedrum, a clutch member of a ratchet nature on the drive shaft, and oog's pivoted on the disk coacting with said clutch member. Y

In a mechanism of the character described, a casing, coaxially arranged drive and driven shafts journaled Within the casing, increasing gearing Within the casx connected with the drive shaft, a drum connected ivith the increasing gearing and L reduced speed with respect' to rotating,` at a reduced speed with respect to the drive shaft, a dish vithin the casing on the driven shaft, fly weights carried by the disk and coacting; with the drum, a clutchV member of a ratchet nature on the drive shaft, dogs pivoted on one side of the dish and having lateral lugs c'oacting` With said clutch member, pivoted dogs located at the Vother side of the disk and operatively connected with the first-named dogs, lateral lugs on the second-named dogs, and leaf springs engaging the second named lugs for normally swinging all of the dogs inwardly.

ll. ln a speed regulating mechanism, the combination with the drive and driven shafts, of a friction drum, increasing gear-- ing operated by the driven shaft through the friction drum, a support carried by the driven shaft, normally spring pressed means carried by the support cooperating with the drum for providing' drive connection between the drive and driven shafts at certain speeds, a clutch member carried by the drive shaft, and. means carried by said support and enacting with saidclutch member for providing' a direct drive connection at higher speeds of the driven shaft.
